Wulfenite Value, Price, and Jewelry Information

Although aesthetically magnificent wulfenite crystals are often too thin, soft, and sensitive to cut for jewelry, rare faceted pieces are greatly prized by collectors. The red of wulfenite, especially from the Red Cloud Mine in Arizona, is one of the richest colors in nature.

Yugawaralite Value, Price, and Jewelry Information

Yugawaralite is a very rare colorless to pinkish zeolite mineral. Little facetable material exists, so a cut yugawaralite would be a prized addition to a gem collection.

Updated Rainbow: Online Faceting Designs and Diagrams

Jeff Graham’s original Rainbow gem design has always been popular. However, inexperienced faceters have found it very challenging. This updated Rainbow should prove easier to facet.

Pyroxmangite Value, Price, and Jewelry Information

Pyroxmangite grains are rare, seldom clean enough to facet, and difficult to cut. However, when cut, they are extremely beautiful and rich in color.

Barite Value, Price, and Jewelry Information

Massive white barite (also called known as baryte) looks like marble and could be used for decorative purposes. In spite of the abundance of good crystals, cut barites aren’t commonly seen, especially in rich colors.

Phosphophyllite Value, Price, and Jewelry Information

Renowned for its delicate blue-green shades, phosphophyllite’s beauty is enhanced by expert cutting. Unfortunately, this gem is quite fragile and difficult to cut, and few large facetable crystals exist. This makes phosphophyllite one of the more desirable — and expensive — collector’s gemstones.
